ORDER AND REASONS
This matter is before the Court on the motion of plaintiffs to dismiss the third-party claim of the New Orleans Parish Levee Board (Levee Board) against the National Weather Service for lack of subject matter jurisdiction, and to remand the main demand to the Civil District Court for the Parish of Orleans, the Court of original junsdiction. Following oral argument and considering the record, the memoranda filed by the parties and the law applicable to this issue, the Court granted plaintiffs’ motion for the reasons hereinafter set out.
Plaintiffs, residents of the Parish of Orleans, Louisiana, filed a class action damage suit against the Levee Board, the City of New Orleans and the State of Louisiana.on January 21, 1983 in Civil District Court for the Parish of Orleans. The basis of plaintiffs’ suit is the alleged negligent failure of the Levee Board to close the flood gates on the Industrial Canal which resulted in flooding in the Florida-Desire area of New Orleans and property damage to the plaintiffs. At the time of filing, plaintiffs’ suit was completely non-diverse and presented no federal question, nor did it involve any federal agency of the United States of America. On March 14, 1983, the Orleans Parish Levee Board filed a third-party petition in the state court suit against the National Weather Service, an agency of the United States of America. The United States of America removed the entire state court proceeding to the United States District Court on March 24, 1983.
Plaintiffs argue that removal was improper as the Civil District Court did not have jurisdiction over the United States of America because the federal courts have exclusive jurisdiction over actions brought under the Federal Tort Claims Act, 28 U.S.C. 1343(b). Since removal is derivative in nature, plaintiffs contend that this Court cannot acquire jurisdiction from a court which did not have jurisdiction.
Removal procedures generally permit removal if the case might have been brought in federal court originally, and if it is also within the subject matter jurisdiction of the state court in which it has been commenced. 28 U.S.C. 1441.1
*1354“(I)t is well settled that if the state court lacks jurisdiction over the subject matter or the parties, the federal court acquires none upon removal, even though the federal court would have had jurisdiction if the suit had originated there.”
Arizona v. Manypenny, 451 U.S. 232, 101 S.Ct. 1657, 1664, fn. 17, 68 L.Ed.2d 58 (1981). Where an action, even a third-party claim, is asserted which is within the exclusive jurisdiction of the federal district courts, the state court will not have jurisdiction over the claim. Goodrich v. Burlington Northern R.R. Co., 701 F.2d 129 (10th Cir.1983) (third-party complaint against the Postal Service under the Federal Tort Claims Act held within the exclusive jurisdiction of the federal courts, and therefore, state court did not have jurisdiction over claim and federal court was without jurisdiction upon removal). The jurisdiction of a federal court over a removed case can be no greater than that of the state court whence the case came. Armstrong v. Alabama Power Co., 667 F.2d 1385 (11th Cir. 1982).
Application of this case law to the instant case results in the finding that this case was removed improvidently and without jurisdiction. The attempt by the Levee Board to join a United States agency did not confer jurisdiction of that claim on the state court as the Act’s exclusive federal jurisdiction absolutely precludes the state court’s exercise of jurisdiction. This Court therefore acquired no derivative jurisdiction over the agency upon removal. The Levee Board attempts to characterize plaintiffs’ complaint as an “artful” attempt to avoid federal court, but there is no indication that this is, in fact, plaintiffs’ motivation. Plaintiffs have a right to choose a state forum and we cannot disturb that right where a ground for removal is not contained in plaintiff’s complaint.
Defendant argues that it would be a judicial waste of time to dismiss the third-party demand and remand the case as it will file a third-party demand again in state court naming various employees of the National Weather Service as defendants and will once again remove the action to federal court under 28 U.S.C. 2679(c).2 The Levee Board argues that, as a practical matter, to save judicial time and expense, it should be permitted to amend its third-party com*1355plaint to name these employees and thus save federal jurisdiction. However, “(it) is a fundamental principle of law that whether subject matter jurisdiction exists is a question answered by looking to the complaint as it existed at the time the petition for removal was filed.” IMFC Professional, etc. v. Latin Am. Home Health, 676 F.2d 152, 157 (5th Cir.1982), citing In re Carter, 618 F.2d 1093, 1101 (5th Cir.1980). This Court is thus precluded from creating jurisdiction through amendment where jurisdiction did not initially exist. It is clear that a complaint may not be amended after an improper removal to state a separable controversy. IMFC Professional, supra.
Accordingly, plaintiffs’ motion to dismiss the third-party claim of the Levee Board against the National Weather Service is granted and the main demand is hereby remanded to Civil District Court for the Parish of Orleans. As this Court has no jurisdiction over the third-party claim against the National Weather Service, the motion of that defendant to dismiss is moot.
